CANDY-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 789,808, dated May 16,1 905.

Application filed December 5, 1904. Serial No. 235,582.

To (tZZ whom, it may cmwcrn:

Be it known that I, WILLIAM T. HUDSON, a citizen of the United States,residing at Atlanta, in the county of Fulton and State of Georgia, haveinvented new and useful Improvements in (landy-VVor-king Machines, ofwhich the following is a specification.

My invention pertains to candy-Working machines, and contemplates theprovision of a compact and durable machine calculated to work twobatches of candy with approximately the same power that it ordinarilytakes to work one batch.

Other objects and advantages of the invention will be fully understoodfrom the following description and claims when taken in connection withthe accompanying drawings, forming part of this specification, inwhich-- Figure 1 is a top plan view of the machine constituting thepresent and preferred ernbodiment of my invention. Fig. 2 is a sideelevation of the same, and Fig. 3 is an elevation of the left end of themachine.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to whicl A is the main frame of my novel machine.The said frame is preferably of -metal, and while it may be of anyconstruction compatible with the purposes of my invention I prefer thatit comprise a table a, mounted on legs 6, uprights c, rising from thetable adjacent to one longitudinal edge and the ends thereof, diagonalbraces (Z, interposed between the transverse central portion of thetable and the upper portions of the uprights c, and a support a, risingfrom the table adjacent to the opposite longitudinal edge thereof withreference to the longitudinal edge first mentioned. As best shown inFig. 3, the support 0 is provided in its upper portion with alongitudinally-disposed guidewayf and on its outer side with a lateralbracket g, which is bifurcated for a purpose presently set forth.

B B are short transverse shafts journaled in the upper portions of theuprights 0 and having sprocket-gears lblOOSB on their outer ends. 0 Care heads fixed on the inner ends of the said shafts and each bearinggrabs i. In

Fig. 1 the two grabs complementary to each head C are shown as restingone above the other.

D D are disks fixed on the shafts B and having notcheslc in theirperimeters designed to be engaged by pawls l, carried by the loosesprocket-gears h.

E is a primary shaft journaled in the lower transverse central portionof the main frame A and bearing a sprocket-gear m at one of its ends,and F is a sprocket-belt arranged on and connecting the sprocket-gears7e, and the sprocket-gear m. In virtue of this construction it will beobserved that when the primary shaft E is rotated in one direction thepawl Z of one of the gears it will engage the notch in in one of thedisks D and through the medium of said disk rotate one of the shafts Bin a corresponding direction, while when said shaft E is rotated in theopposite direction the pawl Z, carried by the gear it on the other shaftB, will engage the notch in the disk D on the shaft, and thereby rotatethe said shaft in the same direction as the primary shaft E. It willalso be noted that when the primary shaft E is rotated toward the left,Fig. 2, the shaft B at the left of said Fig. 2 will be turned toward theleft and the shaft B at the right of the figure will remain at rest,while when the shaft E is rotated toward the right the shaft B at theright of the figure will be turned toward the right, while the shaft Bat the left of the figure will remain idle.

G is a band-pulley loosely mounted on the primary shaft E and designedto receive a crossed band from a motor. (Not shown.) H is a band-pulleywhich is also loosely mounted on the shaft E and is designed to receivea straight band from the motor mentioned, and I is a clutch keyed orfeathered on the shaft E, so as to turn therewith and movelongitudinally thereon and designed to engage the pulleys (ir and Halternately. From this it follows that when the clutch is in engagementwith the pulley Gr the primary shaft will be rotated in one direction,while when the clutch is in engagement with the other pulley, H, theprimary shaft will be rotated in the opposite direction; also, that whenthe clutch is midway between and out of engagement with the pulleys Gand H both pulleys will turn loosely on the shaft, and hence the shaftand all of the working parts connected therewith will rest.

J is a slide-bar movable longitudinally in the guideway f of the support0 and having a rack 19 at its under side and also having apertures 7,7*, and r Fig. 1.

K is a bell-crank fulcrumed on the support a so as to swing in-ahorizontal plane and having an aperture 8 in its outer arm.

L is a lever fulcrumed in the bracket 9 of the support 0 so as to swingin the direction of the width of the machine and having its lower armbifurcated to engage the clutch I and also having its upper arm disposedin the aperture 8 of the bell-crank K.

M M are tappets disposed in apertures of the slide-bar J and designed toengage the inner arm of the bell-crank K.

N is a transverse shaft journaled in the support a and bearing a piniona, intermeshed with the rack 19 of the slide-bar J, and also bearing aspur-gear o, and P is a spur-gear fixed on the primary shaft E andintermeshed with the spur-gear Q).

It will be readily noticed that motion will be transmitted from theshaft E to the slidebar J through the medium of the gears I and 1;, theshaft N, and the pinion a. It will also be noticed that when theslide-bar J is moved toward the right the tappet M, acting against theinner arm of the bell-crank K, will throw the clutch I into engagementwith the bandpulley G, and thereby reverse the direction of movement ofthe said slide-bar J, while when the slide-bar J is moved in the reversedirection, or toward the left, the tappet M, acting against the innerarm of the bell-crank, will throw the clutch into engagement with theband-pulley H, and thereby reverse the slide-bar J, so as to cause thesame to again move rectilinearly toward the right. It will further benoticed that incident to the rectilinear movement of the slide-bar Jtoward the left the shaft B at the left will remain idle and thatincident to the rectilinear movement of said slide-bar toward the rightthe shaft B at the right will remain idle. However, on the movement ofthe slide-bar toward the right the shaft B at the left will be rotated,and on the movement of said slide-bar toward the left the shaft B at theright will be rotated.

In addition to the features before mentioncd the slide-bar J is providedwith grabs T T, which extend laterally inward therefrom and three (moreor less) transverse apertures t, t, and t to receive the said grabs.

In the practical use of my novel machine the grab T operates inconnection with the grabs complementary to the shaft B at the left, andthe grab T operates in connection with the grabs complementary to theshaft B at the right. It will also be noticed that on the movement ofthe slide-bar J toward the left its grabT will pass through between thegrabs a 11 of the shaft B at the left, which shaft B is then idle. Onthe movement of the slidebar J toward the right, however, the head C ofthe shaft B at the left will make two revolutions and recoil the candy.On the said movement of the slide-bar J toward the right its grab Tpasses immediately over the grab t'and not between the grabs 11 and i.The movement of the bar J toward the left operates to pull the candy onthe grabs complementary to the shaft B at theleft, which shaft is thenidle, as before described. The movement of said bar J toward the rightoperates to pull the candy on the grabs complementary to the shaft B atthe right, which shaft is then idle, as before described, and on themovement of the bar J toward the left the head C complementary to theshaft B at the right makes two revolutions, and hence its grabs recoilthe candy. From this description it will be apparent that incident tothe pulling of the batch of candy at one end of the machine the batch ofcandy at the opposite end thereof is recoiled, and as it only takesabout one thirty-second of one horse-power to recoil the candy and onehorse-power to pull the same it will be appreciated that my novelmachine will work two batches of candy with approximately the same powerthat it ordinarily takes to work one batch, which is an importantdesideratum. When it is desired for the machine to have a long pullingstroke, the grab T is placed in the aperture 6 of the slide-bar J, whilewhen a short pulling stroke is desired said grab T is placed in theaperture t For the same purpose the tappet M is transferred from theaperture r to the aperture W and vice versa. The long stroke accumulatesmore air in the candy, and hence makes it lighter in weight than whenpulled by the short stroke. The short stroke is designed especially foruse in the pulling of stick-candy, in which but a comparatively smallquantity of air is desirable. From this it follows that my novel machineis designed for pulling all kinds of candy.

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order to impart a full, clear, and exactunderstanding of the said embodiment. I do not desire, however, to beunderstood as confining myself to such specific construction andrelative arrangement of parts, as such changes or modifications may bemade in practice as fairly fall within the scope of my invention asclaimed.
